Home battery installation day is usually shorter than people expect, but the weeks around it decide whether it goes smoothly. In South Australia the installer needs network approval before the work, the electrical certificate arrives after it, and your meter may need changing in between.
This guide walks through what happens, who does what and what to check before the installer leaves. If you are comparing quotes from solar battery installers in Adelaide, use it as a checklist. Each timeframe below comes from a named source, and anything illustrative is labelled.
Key takeaways
- Amber says one to two days is typical for a home with solar and a battery. Tesla says a Powerwall install takes one full day, with power off for at least four hours.
- Your installer applies for SA Power Networks approval. It is tied to your NMI and valid for 6 months.
- The Clean Energy Regulator says the installer must be Solar Accreditation Australia accredited with a battery endorsement. Ask to see it.
- RENEW’s summary of AS/NZS 5139 requires 600 mm clear each side and 900 mm above the battery.
- In South Australia the electrical contractor must issue an electronic certificate of compliance within 30 days of finishing.
What happens before home battery installation day?
Preparation starts with a site assessment and a quote that states where the battery will go, according to the Resilient East installation fact sheet. The Clean Energy Regulator (CER) says the battery must be installed by a Solar Accreditation Australia (SAA) accredited installer with a battery endorsement, and you can check accreditation on SAA’s status page.
The installer then lodges a Small Embedded Generation application through the SA Power Networks portal. SolarQuotes reports that standard proposals can be auto-approved, up to 10 kW of solar inverter plus 10 kW of battery inverter per phase and 30 kW per site, when they meet technical requirements and the area is not constrained. SA Power Networks says the approval is specific to your NMI, valid for 6 months and invalidated if equipment not listed in it is installed.
Check the approval email against your bill. Meter work may follow: the retailer arranges a change or reconfiguration so exports can be read, and SolarQuotes says the system can be installed before or after it.

How long does home battery installation take?
Most installs take one to two days. Amber says a typical home with solar and a battery takes one to two days, Tesla says a Powerwall installation typically takes one full day, and Energy Matters says a simple AC-coupled battery with no wiring or switchboard issues could be finished in half a day.
Plan for part of that time without mains power. Tesla says power is off for at least four hours and possibly longer, depending on the complexity of the electrical work. The Resilient East fact sheet says your retailer should tell you about inconveniences such as blocked driveways or a power shutdown during installation.

Orange: mains power off. Green: power on.
Typical sequence with illustrative proportions, built from Amber, Tesla, RENEW and the Resilient East fact sheet. Your installer’s schedule and outage window will differ.
Ask about backup while the installer is there. Amber notes most residential systems back up only selected circuits such as the fridge, modem and lights, so confirm which circuits you will have. Our guide to home battery backup in a blackout explains what that means in practice.
What does the installer do on site?
Amber lists the core tasks: installing the inverter, usually near the switchboard or battery, mounting and connecting the battery, configuring backup circuits if you chose them, setting up the monitoring app and running full system testing. Resilient East adds that the installer commissions the battery, which may involve registering it with your energy network, and cleans up when finished.
The work must also follow AS/NZS 5139. RENEW’s summary requires at least 600 mm clear either side and 900 mm above, with a non-combustible barrier of the same size when a habitable room is on the other side of the wall. SolarQuotes’ inspector guidance found fire-rated sheeting that stopped short of the required distance and says it should extend at least 600 mm past the battery. Garages may also need a bollard to protect against vehicle impact.
Wall check: what does the clear space look like?
Illustration only, based on RENEW’s summary of AS/NZS 5139 and SolarQuotes inspector guidance. Your battery’s manual may require more. The installer must follow the standard and the manual.
Heat and airflow matter as much as clearances. See our guide to Adelaide home battery heat and placement before you agree a location.
What should you check before the installer leaves?
The CER says to confirm the installer is the right person and ask to see their accreditation and licence. If they are not on site throughout, confirm they will attend the job setup, mid-install and commissioning. Check the system is in good condition and working, and ask for operating instructions.
Ask for a demonstration. SolarQuotes says the installer should demonstrate the system and explain how to turn it on. Tesla asks you to confirm you can see and operate the system in its app before the installers leave, and the Resilient East fact sheet says you should be shown how to read the battery display or monitoring app.

What happens after installation day?
The electrical contractor must issue an electronic certificate of compliance (eCoC) within 30 days of completing electrical work, according to the SA Government. It is emailed to you, and the SA Government warns that without one insurers could refuse a claim if the work causes a fire or damage. The installer must also complete and close out the SA Power Networks approval within its 6 month validity.
Metering is the step most likely to delay switch-on. SA Power Networks says an installation should not be turned on until a meter that can read exports is installed, and SolarQuotes says that without an agreed date the retailer must complete a simple meter exchange within 15 business days or a new connection within 6 business days. For the rebate, the CER says the battery must stay at the property until the later of the end of its warranty or the end of 2030, and you can assign your certificates to a registered agent for an upfront discount. Read what you sign first.
Deadline calculator: when should each step be done?
Method: approval validity of 6 months (SA Power Networks), eCoC within 30 days of completion (SA Government), and 15 or 6 business days for meter work when no date is agreed (SolarQuotes). Weekends are excluded from business days, public holidays are not. Indicative only.

How should you prepare for home battery installation day?
- Check the SA Power Networks approval email matches your bill and NMI.
- Be home or arrange access. Tesla asks customers to be home to give installers access if needed.
- Clear the driveway and the wall area, and warn the household about the outage. Plan for at least four hours without power, as Tesla advises for a Powerwall.
- Download the battery’s monitoring app before the day so you can test it at handover.
- Know who will be on site and when, as the CER suggests.
- Photograph the finished install and file the manuals, certificates and warranties together. That last step is a practical tip, not a requirement.
Frequently asked questions
How long does a home battery installation take?
Amber says one to two days is typical for a home with solar and a battery. Tesla says a Powerwall installation typically takes one full day, and Energy Matters says a simple AC-coupled battery with no wiring or switchboard issues could be done in half a day. Switchboard work or meter changes can add time.
Will my power go off during a battery installation?
Yes, for part of the job. Tesla says power is off for at least four hours for a Powerwall installation and possibly longer, depending on the electrical work involved. Your retailer should tell you about shutdowns in advance, so ask for the likely outage window and plan around fridges, work-from-home needs and medical equipment.
Do I need to be home on installation day?
Tesla asks customers to be home to give access if needed. Even if your installer does not, being there for the handover helps. The Clean Energy Regulator suggests confirming the installer’s accreditation, checking the system is working and asking for operating instructions before the work is signed off.
What paperwork should I receive after a battery installation in SA?
Expect an electronic certificate of compliance within 30 days of completion, your SA Power Networks approval details, manuals, warranties and a compliance statement, according to the SA Government, SA Power Networks and Energy Matters. The Clean Energy Regulator says installers must provide written documentation about the battery and installation.
Does a battery installation need SA Power Networks approval?
Yes. The installer lodges an application through the SA Power Networks portal. SA Power Networks says adding a battery to an existing system needs a new application, and approval is valid for 6 months. It is specific to your NMI, and installing equipment not listed in it invalidates the approval.
What if the installer is not on site the whole time?
The Clean Energy Regulator says to confirm they will attend the job setup, mid-install and commissioning. It also says inspections are voluntary and can only go ahead with your written consent. If you are unsure who is responsible, ask for the installer’s name, accreditation and contact details before work starts.
